Overview: Examining and exporting application statistics

This implementation describes how to view application statistics on the BIG-IP® system. It describes how you can examine the statistics in the Analytics charts when Application Visibility and Reporting (AVR) is provisioned. Analytics charts display statistical information about traffic on your system, including the following details:

  • Overview
  • Transactions
  • Latency
  • Throughput
  • Sessions

The system updates the Analytics statistics every five minutes (you can refresh the charts periodically to see the updates). The Analytics Overview provides a summary of the most frequent recent types of application traffic, such as the top virtual servers, top URLS, top pool members, and so on. You can customize the Analytics Overview so that it shows the specific type of data you are interested in. You can also export the reports to a PDF or CSV file, or send the reports to one or more email addresses.

Note: The displayed Analytics statistics are rounded up to two digits, and might be slightly inaccurate.

Examining application statistics

Before you can look at the application statistics, you need to have created an Analytics profile so that the system is capturing the application statistics internally on the BIG-IP® system. You must associate the Analytics profile with one or more virtual servers (in the Analytics profile or in the virtual server). If you created an iApp application service, you can use the provided template to associate the virtual server. To view Analytics statistics properly, you must have Adobe Flash Player installed on the computer where you plan to view them.
You can review charts that show statistical information about traffic to your web applications. The charts provide visibility into application behavior, user experience, transactions, and data center resource usage.
  1. On the Main tab, click Statistics > Analytics. The Analytics Overview screen opens.
  2. Optionally, from the Time Period list (Last Hour, Last Day, Last Week, or Last Month) or the configuration gear settings for a widget, adjust the time range, data measurements, and format of data to display.
  3. From the menu bar, select the type of statistics you want to view.
    Select this option To see these application statistics
    Overview Top statistical information about traffic on your system or managed systems, such as the top virtual servers, top URLs accessed, and top applications. You can customize the information that is displayed.
    Transactions The HTTP transaction rate (transactions per second) passing through the web applications, and the number of transactions to and from the web applications.
    Latency > Server Latency How long it takes in milliseconds from the time a request arrives at the virtual server until a response arrives at the virtual server.
    Latency > Page Load Time How long it takes in milliseconds for a whole web page to fully load on a client's browser from the time the user clicks a link or enters a web address until the web page is completely displayed.
    Throughput > Request Throughput HTTP request throughput in bits per second.
    Throughput > Response Throughput HTTP response throughput in bits per second.
    Sessions > New Sessions The number of transactions that open new sessions in sessions per second.
    Sessions > Concurrent Sessions The total number of open and active sessions at a given time, until they time-out.
    The charts display information based on the settings you enabled in the Analytics profile.
  4. To view information specific to a particular network object type, select an option from the View By list. You can also click Expand Advanced Filters to filter the information that is displayed.
  5. To focus in on the specific details you want more information about, click the chart or the details. The system refreshes the charts and displays information about the item.
  6. On the screen, the system displays the path you followed to reach the current display, including the items you clicked. For example, to review throughput details for a particular virtual server, follow these steps:
    1. From the Throughput menu, choose Request Throughput.
    2. From the View By list, select Virtual Servers. The charts show throughput statistics for all virtual servers on this BIG-IP system. You can point on the charts to display specific numbers.
    3. Click the virtual server you want more information about. You can either click a part of the pie chart or click the name of the virtual server in the Details table. The charts show throughput statistics for that virtual server, and shows the path you used to display the information.
    4. To view information about other applications or retrace your path, click a link (in blue) in the path displayed by the charts.
    As you drill down into the statistics, you can locate more details and view information about a specific item on the charts.
You can continue to review the collected metrics on the system viewing transactions, latency, throughput, and sessions. As a result, you become more familiar with the system, applications, resource utilization, and more, and you can view the statistics in clear graphical charts, and troubleshoot the system as needed.

Exporting or emailing application statistics

To send reports by email, the default analytics profile must specify an SMTP configuration ( Local Traffic > Profiles > Analytics ).
You can export or email charts that show application statistics.
  1. On the Main tab, click Statistics > Analytics. The Analytics Overview screen opens.
  2. Display the charts that show the information you want, clicking any of the menu bar options and adjusting the content as needed.
  3. On the upper right of the charts screen, click Export.
    Tip: You can also export any single report widget from the Analytics Overview screen. Click the widget configuration icon for the report and select Export.
    The Choose Export Options popup screen opens.
  4. Select the appropriate options.
    For this option Do this
    Export the data in option format Specify the export format:
    • Select PDF to save the information in a graphical format to a PDF file.
    • Select CSV (Time Series) to export the information to a text file including specific information for time increments.
    • Select CSV (Details Table) to export the information to a text file providing summary details.
    If exporting the entire Overview screen, the information is saved only in PDF format (no export format options are available). When exporting widgets, the format options are PDF or CSV (only one CSV format is provided).
    Save the report file on your computer Select this option to save or open the file containing the report.
    Send the report file as an attachment to the following E-mail address(es) Type one or more email addresses (separated by comma or semicolon) to which to send the report.
  5. Click Export. The system saves the report to a file or emails the file to the specified recipients. If SMTP is not configured (when sending reports by email), you receive a message that SMTP must be set up before you can send the reports.

Creating an SMTP configuration

If you want the BIG-IP system to send email or alerts, you need to create an SMTP server configuration.
  1. On the Main tab, click System > Configuration > Device > SMTP.
  2. Click Create. The New SMTP Configuration screen opens.
  3. In the Name field, type a name for the SMTP configuration.
  4. In the SMTP Server Host Name field, type the IP address or the fully qualified domain name (FQDN) of the SMTP server. If using the FQDN, make sure the DNS server is on the DNS lookup server list, and configure the DNS server on the BIG-IP system ( System > Configuration > Device > DNS ).
  5. In the SMTP Server Port Number field, type the port number used for the SMTP server. Typically, the default SMTP port numbers are 25 (unencrypted or TLS), 465 (SSL encrypted), or 587 (TLS encrypted).
  6. In the Local Host Name field, type the host name used in SMTP headers in the format of an FQDN; for example, bigip.net. This setting does not refer to the host name of the BIG-IP system.
  7. In the From Address field, type the email address that the email is being sent from. This is the address that the recipient sees. Because the BIG-IP system does not accept reply email, use either a valid email address or a from address such as do-not-reply@bigip.net.
  8. To encrypt traffic between the BIG-IP system and the SMTP server, for Encrypted Connection, select the type of encryption, SSL (Secure Sockets Layer) or TLS (Transport Layer Security).
  9. To require authentication on the SMTP server, for Use Authentication, select the Enabled check box, and type the user name and password.
  10. Click Finish.
The SMTP configuration you created is now available for use. For example, you can use it when emailing statistics.
After you create the SMTP configuration, you need to specify it in the appropriate profile. You can create more than one SMTP configuration, if needed.
